“One is equally foolish to mistake mythology for technical descriptions in Yoga texts which mention clearly that hunger and thrist can be ended if one practices a certain yoga technique.”
Yes, that is possible. And I know this from direct experience, as I have awakened the same siddhi. But if you consider something like “flying in the sky”, then you are simply being idiotic in the same way that a Christian is being idiotic by actually believing that there was a Tree of Knowledge and Tree of Life in the Garden of Eden. And the fact that you are so desperate to cling to these siddhis reflects your own vulgar mind - which is far more interested in lust for power rather than wisdom. Unless you are willing to surrender and surrender totally, become absolutely powerless to a force which is beyond your own limited ego, then you have yet to realize what is needed for communion with the Way.
“There exists plenty of accounts of yogis throughut yoga lore who have demonstrated these abilities.”
It is one’s own childish imagination which wants to believe just about anything that crosses one’s path without question, as long as it appeals to one’s ego. Stories are just stories, and it does not matter where they come from. If you simply accept them without question, then you are not different than any dogmatic person who accepts things on the basis of blind belief. And of course, one will try to bend one’s logic according to one’s beliefs. Whatever has yet to enter into one’s own experience has no relevance whatsoever. And even if such a thing was possible, you still have to live in one and the same present moment. The moment you have lost contact with the present in your awareness, you have lost contact with the whole existence. Outside of this, there is no religion.
"Levitation has been elevated from being pure science fiction to science fact, according to a study reported today by physicists. "
It does not require a scientific experiment to prove that levitation in nature is possible. All that you need to do is swim in water to see that. Those experiments they were doing was through the aid of scientific technology, and it is not in the intention of nature that the human body should levitate or have the potential to levitate, just as it is not in the nature of the human body to fly in the air. Try as one may - you are never going to grow wings, regardless of even infinite siddhis that one may awaken.
"In earlier work the same team of theoretical physicists showed that invisibility cloaks are feasible. "
Yes, they have already been invented and put to use. And their use depends on external technology. The human body cannot become invisible, although it is possible to awaken a state of consciousness where it will make you less visible to others in their experience.
